FREDERIC S. WILLIAMS, OF AMSTERDAM, NEW YORK, ASSIGNOR TO KLAUDER- WELDON DYEING MACHINE COMPANY, OF AMSTERDAM, NEW YORK, A COR- PORATION OF NEW YORK.

DYEING-MAGHINE.

Specification of Letters Patent.

Patented Oct.10, 1916.

To all whom it may concern Be it known that I, FREDERIC S. VVIL- LIAMS, a citizen of the United States, residing. at Amsterdam, in the county of Montgomery and State of New York, have invented certain new and useful Improvements in Dyeing-Machines, of which the following is a full, clear, and exact desciption, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to dyeing machines, washing machines, and the like, and with respect to its more specific features, to machines of the type employing rotatable yarn sticks.

One of the objects of the invention is the provision of a simple and eflicient tripping mechanism.

Another object of the invention is the provision of a practical tripping mechanism adapted to effectively cause rotation of the yarn sticks as the machine operates to dye materials and which also is of a character to avoid fracture of the machine parts in the event of substantial obstruction to the normal rotation of the yarn sticks.

Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings, forming a part of this specification and wherein sim ilar reference characters refer to similar parts throughout the several views, Figure 1 is a perspective View of a portion of a dyeing machine embodying the invention; Fig. 2 represents diagrammatically the relation of the trip and the yarn carrier when the latter first contacts the trip; Fig. 3 is a diagrammatic representation of the parts shown in Fig. 2, when the yarn carrier is obstructed and has been translated further relative to the trip; and Fig. 4: is a diagrammatic representation of the position of the parts as the yarn carrier is translated in a direction reverse to that in normal dyeiliteferring now more specifically to the drawings, the numeral 1 indicates a casing adapted to contain dye liquor, and 2 indicates a portion of a reel rotatably mounted so as to dip into the dye liquor. Supported by the reel are the yarn carriers comprising the yarn sticks 3 and 4, arranged in sets on the reel as usual. The outer sticks 3 are preferably square in cross-section and their square ends are received in square sockets, in a rotatable member 6, having arms 7. The members 6 are rotatably mounted on the reel, and are adapted to be rotated in one direction by a trip here inafter described, reverse rotation of said members being prevented by pawls 8, plvoted on the reel and engaging ratchet teeth 9, on the rotatable members 6. The reel may be rotated by any suitable means, preferably being coupled with a motor so as to be automatically rotated, and thereby translate in a circular path the yarn carried on the sets of sticks, the yarn being thereby carried into and out of the dye liquor as the reel-rotates. When the yarn is held in stationary position on the yarn sticks 3 and l, these sticks in a measure prevent contact of the dye liquor with that portion of the yarn in contact with the stick, resulting in non-uniform dyeing. Hence in this class of dyeing machines it is desirable to move the yarn relative to the sticks so as to equally expose all portions thereof to intimate contact with the dye liquor.

In order to effect this movement of the yarn, a trip 10 is provided, with which trip the arms 7 cooperate, being brought into contact with a projecting portion 11 thereof as they are translated by the reel. The trip 10, in the normal dyeing operation, depends in the translatory path of one or the other of the arms 7, and is designed to offer such resistance to the passage of said arms that the member 6 will be partially rotated by the trip in passing thereby. Should the yarn become entangled in any manner so as to obstruct or prevent rotation of the member 6 by said trip, or should the rotatable member 6 stic or be otherwise obstructed or prevented from rotating, there is a tendency to abnormally strain the mechanism, which frequently results in fracture. of portions thereof, and especially of the arms 7. The main object of the present invention is to provide a trip mechanism which will offer sufiicient resistance to the passage of the arms 7 to effect the partial rotation of the members 6, and which is capably of yielding under abnormal strain, so as to avoid the fracture of the mechanism.

In the present embodiment a horizontal rotatable shaft 12, is journaled in a bracket 13, fastened to a suitable part of the frame of the machine. The trip 10 is so connected to the shaft 12 as to rotate said shaft under certain conditions, and preferably this connection involves an eccentric pivoting of the trip relative to the axis of the shaft 12.

This eccentric pivoting is accomplished by pivoting the trip at 14, to a bifurcated arm 15 mounted to rotate with the shaft 12, said arm being embodied in a clevis removably fixed to one end of the shaft by a set-screw 16. Also connected to the shaft 12, so as to rotate therewith are abutment faces 17 and 18, transversely disposed relative to said shaft, and respectively on opposite sides of the line joining the pivotal axes of the shaft and the trip, these faces being opposite similar faces 19 and 20 on the trip. It may here be noted that the trip is comprised in an angle lever, the arm 21 of which extends substantially horizontally and serves to gravitatively urge the arm or trip 10 in a direction to cause the abutment face 19 to approach the face 17. The abutment faces 17 and 18 are preferably provided as a part of the clevis or arm 15, with which they may be cast.

On the opposite end of the shaft 12 is fastened a lever 22 so as to rotate with the shaft 12, and a weight 23 is carried by the lever 22 and may be positioned at different points thereon in order to vary the efiective leverage. The numeral 24 indicates a stop, preferably a cushioned stop, carried by the bracket 13, and which is so positioned that the lever 22 rests thereon when in its lower position.

The drawings show the parts in operative position, and it will be noted that as the reel rotates, the outermost of the arms 7 will successively come into contact with the trip 10. If there is no abnormal obstruction to the rotation of the star-wheel, comprised by the member 6 and the arms 7, in the direction indicated by the arrow a, the translatory movement thereof past the trip will result in a partial rotation of the star-wheel and in consequence a partial rotation of the yarn stick carried thereby. Should the rotation of the star'wheel in the direction mentioned be prevented for any reason, the translatory movement of the arm 7 will cause the trip 10 to tend to rotate around its pivotal axis in the clevis 15, but the face 19 being in contact with the stop face 17, such tendency will be transmitted to the shaft 12 and the result will be to cause the weighted lever 22 to rise, and in this wise the trip will be forced aside by the arm 7 and eventually will escape or wipe past the end of said arm, whereupon it will be restored to its normal operative position, the lever again assuming its lower position against the stop 24. Thus abnormal resistance to the rotation of the star-wheel will cause the forcing aside of the trip 10 under a yielding or gravitative resistance, and there is practically no danger of fracture of any of the parts of the operating mechanism. Also the trip 10 is restored to position in the path of a succeeding star-wheel arm and will effect partial rotation thereof in the usual manner unless the same is obstructed as explained, the effective leverage of the weighted lever being suflicient to cause the partial rotation of the star-wheels, when abnormal resistance to such rotation is not encountered.

It is at times desirable to rotate the reel 2 in a reverse direction to that normally employed in dyeing and it will be noticed that though the star-wheels are prevented from reverse rotation by the pawls 8, nevertheless the trip 10 is arranged to freely rotate around its axis in a direction opposite to that above explained, so that said trip offers practically no obstruction to the reverse rotation of the reels. The stop face 18 is designed to cooperate with the face20 to arrest the reverse movement of the trip, so as to prevent the same being turned completely over'or into a position in which the arm 21 might operate to hold the trip out of operative position.

Thus, by the above described construction are accomplished, among others, the objects hereinbefore referred to.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description 'or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. I
